Call my doctor or no 😬😬

Sooooo I’m 19 weeks and 1 day today. I’ve been feeling off the last few days. I was diagnosed with a heart murmur as a kid but it went away as I got older, but the last 3 days or so I’ve started to feel as I did when I was dealing with it as a kid. I’m just super lethargic, dizzy, not nauseous but ready to throw up on a flip of a switch, and like something my chest just isn’t quite right. My doctor told me in the beginning of my pregnancy that if I feel the murmur starting to come back up she’d send me too a cardio specialist. But the thing is almost all those symptoms are kinda normal for pregnancy except the chest feeling. But I also struggle with anxiety so I’m kinda lost if I should call my doctor or just wait it out😬😬 I honestly hate feeling like this and just wanna feel normal again 😭 Helppp please 🙏🏼
